SPECIFICATION forming part of Letters Patent No. 611,379, dated September 2'?, 1898.

Application filed December 4, 1896. Serial No. 614,484. (No model.)

To a/ZZ whom it may concern:

Be it known that I, MoNNosUKE HIGUCHI, a citizen of the Empire of Japan, residing at Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Type-Writers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in type-writers, the object being to provide a construction in a machine of this kind whereby the extent of movement of the carriage carrying the cylinder varies in proportion to the width of the letter that is printed, whereby the spacing of the letters instead of being uniform withoutregard to the width of the letter conforms to the width ofthe letter."

The invention consists in the features of construction hereinafter fully described, and

pointed out in the appended claims.

In the accompanying drawings, forming a part of this specification, Figure 1.is a per-- spective view of a portion of the operative parts of a type-writer constructed in accordance with this invention. In this view only three keys are illustrated and only the toothed rack is shown, since this invention relates only to these parts. Fig. 2 is a perspective view, taken on an enlarged scale, of a portion of the toothed rack and the immediate devices for controlling the extent of movement of the same. In this view the support for the pivoted detent and the regulating-dog is shown in dotted lines. Fig. 3 is a perspective view taken from the opposite side of the parts shown in Fig. 2 and illustrating the support for the detent and dog in full lines and the toothed rack in dotted lines. is a top .plan of the detent and levers in detail and with the regulatingdog removed. Fig. 5 is a perspective view taken from the under side of the regulating-cog. Fig. 6 is a vertical section through the detent and regulating-dog, illustrating thenormal position of the parts. Fig. 7 is a similar view illustrating the position of these parts when the key that moves the carriage three spaces is pressed. Figs. 8, 9, l0, and 11 are similar views showing the position of these parts Fig. 4.

when the keys for moving the carriage one and two spaces are pressed. Fig. 12 is a fragmentary perspective view illustrating the connection between the sidesof the arms 4 and 5 and the rods l2.

In accordance with the principle involved by this invention it is intended to construct a type-writer in which, as above stated, the carriage is moved according to the Width of the letter. In type-writers in general use the carriage is moved the same distance for each letter, and consequently wide letters-such as all the capitals except I and .I, small m and w, and some figures-receive the same space as small letters and characters, Cif, 6(1)?) (jH ((1,79 i6 t, ((50., letters also of medium width, such as the capital I and .I, and the remaining small let-ters. This of course produces a certain cramped or uneven appearance in the printing, as seen in all type-writing. The alphabet can be divided practicallyinto letters of three different widths, and the characters used canv also be subdivided in this manner, and it is obviousthatwhenthepijnting is done with the space varying according to the width of the letters a more .symmetrical and legible writing is afforded. In this invention the alphabet and characters are so divided, and for the purpose of illustration I have selected three characters-namely, small 1n, a, and i. In printing to attain the best effects the letter small a should have twice the space occupied by small i, while 1n should have three times the space, and I will now proceed to describe the mechanism whereby this is accomplished.

In said drawings lthe frame of the typewriter is indicated by l, while a portion of the carriage is indicated by 2. Attached to this carriage is a toothed rack 3 of ordinary construction. These parts do not form a part of this invention, and therefore only sufticient portions thereof will be shown to illustrate the use and operation of my invention. It is understood, of course, that it might be desirable in connection with certain styles of printing to subdivide the alphabet into more IOO than three divisions, although it is thought the invention limited, except in the claims for the specific construction, to this arrangement. Y

vMounted upon the frame 1 are three pivotedarms 4, 5, and 6. These arms are provided at their forward or swinging ends with cross-pieces 7. The said arms are pivoted concentrically and extend parallel with each other. The key-levers 8, 9, and 10 are constructed in the usual manner-that is to say, they are pivoted to the frame of the machine to operate the type in any approved manner. These key-levers, however, are provided with downwardly-extending projections 1l, situated to engage thecross-pieces 7 of the arm.

.In the instance illustrated the key for the letter m is mounted upon the key-lever 8, and the projection l1 of this key-lever Sis situated to enga-'ge the cross-piece of the arm 4, and likewise the key-levers for a and i are arranged to operate arms 5 and 6, respectively. The sides of the arms 4, 5, and 6 are connected by rods 12, adjacent to their pivots. The connection between the sides of these arms ris such that the movement of one arm does not interfere with the others. As a convenient construction for this purpose the sides of the arm 4 which are outermost are provided with the curved brackets 13, which extend downwardly beneath the arms 5 and 6 andv then'upwardly on the inner side of said arm 6, whereby it is connected with the rod 12. The arm 5 is provided with a similar bracket 13, which passes around the arm 6. The rod 12 for the inner arin 6 is connected directly with said arm. An overhanging bracket 14 is rigidly attached to the frame of the machine adjacent to the toothed rack 3 and is bifurcated at its upward end in the manner shown.

The det-ent 15 is mounted upon a horizontal' pivot extendingthroughthesame and through the bifurcated end portions of the bracket 14, and is provided with a rearwardly-extending finger 16. Secured to the rear side of the bracket -14 are the downwardly and upwardly facing stops 17 and 18. The end of the finger 16 is situated between these stops 17 and 18, whereby thepivotal movement of the detent is limited. The upper or downwardly facing stop 17 extends across the face of the bracket to limit the forward movement of the operating-levers 19 and 20, hereinafter referred to.

' The pivot-pin 21, between the bracket 14 and detentl, extends through the bifurcated endl portions of the bracket and through the pivot of said detent, while said detent is cut away between its sides to provide an opening 22, as shown in Fig. 4, through which this pivot-pin 21 passes. on the side opposite the tip thereof with an upwardly-extending stop 23, designed to limit the movement of the regulating-dog. Secured also to this side of the detent is a spring 24, arranged to engage the regulating-dog and to press the tip of this regulating-dog to one side of the tip of the detent. Upon the opposite side of the detent is another spring 26,

The said detent isalso providedy that is arranged to engage the side of the regulating-dog 25 when it has been pressed to the full extent by the spring 24. The said detent is also provided with .two slots 27 and 28 to receive the bent ends of the operatinglevers 19 and 20, whichserve to limit the extent of movement on the part of the regulating-dog, and for this purpose the slot 27 is arranged to the rear and to one side of the slot 28, as shown in Fig. 4. The regulatingdog 25 is pivoted at its rear end portion to the rear end portion of the detent and upon a vertical pivot. It is arranged to slide horizontally upon the detent and is provided with a tip that stands in alinement with the top of the detent when the regulating-dog is in contact with the upwardly-projecting stop 23 of said detent. The said dog is provided with two stop-faces 29 and 30. The stopfface 29 is arranged so that when the dog turns upon its pivot the slot 28 near the nearest end of the detent is in the path of this stopface, while the stop-face 30 is arranged to one side of and in the rear of the stop-face 29, and the slot 27 is in the path of this stopface. The end face of the dog is recessed, as shown at 31, to allow the dog to swing on its pivot and without contact with the bent ends of the operating-levers 19 and 20. These projecting levers 19 and 2O are pivoted upon the horizontal pivot 21, that supports the detent, and extend forwardly and are provided with upwardly-extending ends 32 and 33. The upwardly-extending portion of the arm 19 extends through the slot 27, while the end 33 of the arm 2O extends through the slot 28. These operating-levers 19 and 2O extend to the rear and adjacent to the side of the bracket to engage the downward ly-facing stop 17 thereof. Springs 34 are connected with the levers 19 and 20 and with the fingers 16 of the detent and serve to hold these parts normally in contact with the said stop 17. The finger 16 of the detent is connected by means of a rod or wire 35 with the rod 12, extending between the sides of the outer arm 4, while the ends of the levers 19 and 20 are connected by means of rods or wires 35 with the rods 12, connecting the sides of the arms 5 and 6, respectively. In this way it is seen that the pressure upon the key controlling the key-lever 8 draws down the finger 16 through the intermediacy of the projection 11, arm 4, and rods 12 and 35. This moves the finger against the action of the spring 34,

and it is obvious that the movement of the other key-levers 8 and 9 will depress the ends of the operating-levers 19 and 2O in the same manner.

I will now proceed to describe the manner in which the detent and operating-dog control the extent of movement of the toothed rack. To illustrate, it is supposed that the key m is depressed. This turns the detent 15 on its pivot, and therefore lifts the dog 25, so that its tip passes above the teeth of the rack, while the tip of the detent holds the Arack. XVhen the dog is released from the rack, the spring 2l presses it until it is held by the opposing-spring 2 It isunderstood, of course, that the recess 3lA in the under side of the dog permits this dog to move to 011e side without contact with the upwardly-extending ends of the operating-lovers 19 and 20. The parts are so arranged that the extent to which this dog is moved is equal to the space of three teeth upon the'rack 3, and therefore when the key m is released the spring 34 raises the finger 16, thereby throw- -ing the tip of the dog into the correct tooth of the rack 3, rwhereby the spring operating the carriage will move the carriage until the dog comes into contact with the upwardlyextending projection 23 of the detent, which is equal to the space between three teeth.

The positions of the parts in this operation are shown in Figs. G and '7, Fig. 6 showing the normal position, while `inFig. 7 the detent and dog are shown in an inclined position when the detent engages the toothed rack and the dog has risen above the same and has been pressed to. one side of the 'spring 24.

In Figs. 8- and 9 are shown the positions the parts assume when the key ais depressed, and therefore depresses the end of the operating-lever 19. As this operating-leverlQ turns on its pivot the upwardly-extending end 32 thereof passes upwardly through the slot 27, and when .the said lever strikes the -r-ack, while the dog after having risen above the same has been -movedto one side by the spring 24 until its stop-face 30 comes in contact with the end 32 of the lever 19. The extent towhich this upwardly-extending portion- 32 of the lever 19 allows the dog to move is equal tothe space between two teeth, and therefore when the key a is released and the parts brought to their normal position, with the dog in engagement with the toothed rack, ,said dog in moving back into contact with the stop 23 allows the toothed rack to move two spaces. It will be seen that thne movement of the lever 19 .and the detent does not vinterfere with nor cause the lever 2O tov move,

and in moving the lever there is no movement oni-he part of the lever 19. When the lever 20 is moved in the manner described in relation to the liever 19, it is seen that its upwardly-,extending end portion 33 moves into the path 'of the Vstop-face 29 and permits the dog to move under the influence of the spring 24 only one space, and consequently when the dog again engages the toothed rack the cr "riage moves only one 'space before the dog comes in cent-act with the stop 23.
